Careful inspection of the imagery does reveal difference between imagery created from Himawari-8 Imagery over eastern Asia and imagery created from Meteosat imagery over central Asia.  There is a more subtle difference between Meteosat imagery and GOES-16 imagery, chiefly because that seam is over the eastern Atlantic Ocean.  Such differences arise from spectral differences between the satellites.<\/p>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n\n\n\n<p>This <a href=\"https:\/\/cimss.ssec.wisc.edu\/goes\/webapps\/seasons.html\">web page with web apps<\/a> allows anyone to investigate how solar energy varies with the season.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>SSEC\/CIMSS scientists (notably Rick Kohrs) create daily imagery that blends vertical strips of true-color imagery at local Noon, starting near the dateline and proceeding westward.
